SHAFT-LOO P.

SPECIFICATION forming part of Letters Patent No. 577,833, dated March 2,1897.

Application filed Augu t 10, 1896- Serial No. 602,232. (No model.)

mouth, in the county of Scioto and State of Ohio, have invented certainnew and useful Improvements in Shaft-Loops; andI do hereby declare thefollowing to be a full, clear, and exact description of the invention,reference being had to the annexed drawings, which form a part of thisspecification.

My invention comprises a shaft-loop which includes a vertical backplate, an eye at the top thereof, another eye at the bottom, anoutwardly-projecting bearing to support a shaft, a bead or roll at theupper end of said bearing, and a spring which extends down from saidupper eye and has its free end in contact with the back of said bearingand at a point slightly below said roll, the entire device being made ofa single fiat strip of spring metal, as hereinafter more fullydescribed.

In the annexed drawings, Figure 1 is a perspective view of one form ofmy shaft-loop. Fig. 2 is a vertical section of a modification of theinvention.

My loop is made of a single piece or strip of sheet-steel orother metalhaving the proper resilient action; and it consists of a back A, whichis practically straight from end to end, and has at top an eye B and atbottom another eye, B. Bending outwardly and upwardly from this lowereye is a bearing 0, to support a thill or shaft, the top of said bearingbeing formed into a rounded bead or roll 0.

D is a spring extending down from the upper eye B and having its freeend in contact with the inner side of bearing 0 at a point slightlybelow its bead c.

It is customary to attach rings 1) b to the eyes B B, as seen in Fig. 2,in order thatthe 4o loop may be applied to a harness in the same manneras an ordinary loop, and when this is done the thill or shaft E isinserted in a moment. It is necessary only to bring the thill down onthe spring D with sufficient force to overcome its tension, and thensaid spring is pressed back toward the plate A and the thill allowed todrop until it rests upon the bearing 0. The spring then flies out to itsnormal position and prevents accidental disengagement of the shaft.

In the modification of my invention seen in Fig. 2 a small rollerF isprovided for the lower side of the shaft E to play upon.

As my shaft-loop is made entirely of metal, it can be readily plated orjapanned, or it can be enveloped with leather or otherwise ornamented tosuit the demands of the trade.

I claim as my invention- As a new article of manufacture, thewithin-described specific construction of shaftloop, which constructionincludes the back plate A, having eyes B, B, at top and bottom; abearing 0, projecting outwardly and upwardly from the lower eye B; abead or roll 0, at the upper end of said bearing; and a spring D, whichextends down from the upper eye B, and has its free end in contact withthe back of said bearing, and at a point slightly below said roll; theentire device being made of a single, fiat, strip of spring metal, allas herein shown, and set forth.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY A. BIERLEY.
